BS EN 624-2000 pdf download.Specification for dedicated LPG appliances — Room sealed LPG space heating equipment for installation in vehicles and boats.
5.1 Conversion to different gases
The appliance shall be supplied for a single gas category and for a single operating pressure or pressure couple unless where the test pressure range for that category includes the test pressure range for other categories. If this is the case the subsidiary categories may also be stated on the data plate.For example for category 13.. the test pressures for categories 1RP. l37 and ‘3R are covered.
Conversion to another category or pressure or pressure couple is not permitted.
5.2 Materials
The quality and thickness of materials used in the construction of a heater shall be such that the safety characteristics are not altered in use.
In particular, all parts of the heater including controls shall withstand the mechanical, chemical and thermal conditions to which they may be submitted during their use and at ambient temperatures between -20 °C and 60 °C. In normal conditions of use, of cleaning or of adjustment, the materials shall not be liable to any alterations which might impair their performance. Sheet metal parts not made of corrosion-resistant material shall be vitreous enamelled or be covered with another effective protection against corrosion.
Materials containing asbestos shall not be used.
Aluminium gas pipes shall not be used.
All accessible components shall have no sharp edges or corners likely to cause injury during use or maintenance. Mountings for glass components shall be such as to avoid Stresses on the glass during normal use.
The appliance shall be so designed that it is able to absorb vehicle vibrations and relative movements. All parts of the combustion circuit shall be made of corrosion resistant materials or be provided with a permanent protection against corrosion (by, for example, condensate water). If mild steel protected against corrosion is used for parts in contact with exhaust gas. the minimum thickness shall be 1 mm.
The seals with which the exhaust gas comes into contact shall not be adversely affected by moisture or heat (see 5.13).
Non metallic materials which are used as seals and lubricants in the gas path shall be resistant to LPG. Diaphragms and seals shall comply with EN 549.
5.3 Accessibility of components
5.4 Strength of assembly
The construction of a heater shall be such that, during normal conditions of transport, installation, use and maintenance, any displacement of parts. distorbon or deterioration likely to impair its peilormance shall not occur.
5.5 Soundness
5.5.1 Soundness of the gas carrying parts
5.5.1.1 ConstructIon
Holes for screws, pins, etc. intended for the assembly of components shall not open into the gas ways and shall leave a minimum wall thickness of 1 mm.
The soundness of assemblies connected to the gas circuit shall be assured, by means of metal-to- metal joints or joints with seals (e. g. washers. 0-rings or gaskets).
For parts that are not required to be dismantled during normal maintenance, the use of thread sealing compounds complying with EN 751-1 or EN 751-2 is permitted.
Soft solder shall not be used to ensure the soundness of the connections of the gas circuit within the heater.
Removable components or the threaded parts of the pipe work which are likely to be dismantled during normal maintenance shall remain sound after five disconnections, if necessary after changing a gasket. where the manufacturer’s instructions require this.
5.5.1.2 Soundness test
When tested in accordance to 6.5.1.2, the leak detected shall not exceed 40 cm/h.
5.5.2 Soundness of combustion circuit
The heaters, including all parts which serve as the combustion air supply and flue shall form a continuous leakproof arrangement. Any necessary extension pieces shall be fitted and all items, including ducts shall be supplied or specified by the heater manufacturer.
The combustion circuit from the combustion air intake to the entry of the heat exchanger shall not exceed a leakage rate of 1.0 m3/h when tested as in 6.5.2.2.
The combustion circuit from the entry of the heat exchanger to the flue outlet shall not exceed a leakage rate of 0,2 m3/h when tested as in 6.5.2.2.BS EN 624-2000 pdf download.
